Creatine: Strength Gains, Brain Boosts, and Kidney Caution
The Truth About Creatine From an Internist’s Perspective
Creatine is having a major moment. Wellness influencers, athletes, and even biohackers are calling it a must-have for building strength, boosting brain power, and aging well. But is creatine really for everyone?
Let’s talk about what creatine is, how it works, what the benefits are, and why it’s still something you should never start without medical guidance.
What Is Creatine?
Creatine is a natural compound found in your muscles. Your body also makes it in small amounts, and you can get it from foods like red meat and fish. It helps your cells produce energy during short bursts of intense movement, like sprinting or lifting weights.
Creatine is also one of the most studied supplements out there, and for good reason.
Creatine Benefits Everyone Is Talking About
There’s a reason creatine is trending. Studies show that it may help with:
- Muscle growth and strength
- Workout recovery
- Brain performance and focus
- Energy levels
- Healthy aging and bone density
Some research even links creatine to better memory and brain health as we get older.
But Here’s What Many Are Not Talking About
Yes, creatine is generally safe. And no, it has not been proven to cause kidney disease in healthy people.
But that doesn’t mean there are zero concerns. Especially when not everyone is as healthy as they think and some people may not be aware that they have underlying kidney disease.
As an internist, I see the full picture not just the trends. Here’s what you should know:
1. Creatine Raises Creatinine Levels
Creatinine is a waste product that we measure to check how well your kidneys are working. Creatine supplements can make your creatinine levels go up, even if your kidneys are fine.
This is where it gets tricky.
If your doctor sees an elevated creatinine level on your labs and doesn’t know you’re taking creatine, it might lead to unnecessary worry or worse, missed signs of real kidney issues.
2. If You Have Any Kidney Concerns, Be Extra Careful
People with high blood pressure, diabetes, or a family history of kidney disease should be cautious. Even small changes in kidney function matter. That’s why no supplement that affects kidney markers should be taken casually.
3. It’s Not a One-Size-Fits-All Supplement
You may not need it. Or you may need a lower dose. Your doctor can help you decide what’s best for your body.
Creatine is not just about muscles. It impacts metabolism, fluid balance, and how your body clears waste. All of this needs to be considered.
Bottom Line: Creatine Has Benefits, But It’s Not a Free Pass
If you’re thinking about adding creatine to your wellness plan, especially for longevity, brain health, or muscle support, great. But don’t DIY it.
You need monitoring. You need lab work. And you need a doctor who understands both wellness and kidney health.
